RE: FLASH: MD5 hash in F5 action script

[.redstar.]

John,


"what is md5? sorry for the ignorant q."


And why should a seeker of knowledge be assumed to be ignorant ?

In very simple terms, and without attempting formal correctness, MD5 is a

way to transform a sequence of strings (text) into a fix length

representation that uniquely identifies the original text. This can, among

other uses, be useful when you want to send passwords or other sensitive

data (card numbers for example) but do not want to transmit the clear text

version of the data so as to avoid interception.

As MD5 is 'a one way function' you 'cant't' retrieve the original data from

the MD5 hash of the data so interception and recovery of the original data

is 'very hard'.

The basic usage would be to have an entry field for the data and then do

calcMD5(data) and send this over the wire. When you receive it you do the

same on your side with your known local copy of what you expect (the

password for example and compare results for a match.


Hope this helps.
